One: The last man on Earth sat alone in a room. There was a knock on the door. Two: I woke up to find 'You are next' written on my mirror. I live alone.
Here's another. 'The old house was empty. I walked in, the floorboards creaking. A photo on the wall showed a face that looked like mine. The lights flickered. When I looked back at the photo, the face was gone.'
The old house stood alone. Creaking noises filled the night. I saw a shadowy figure. It vanished when I blinked.
She heard a knock on the door. No one was there when she opened it. But there were wet footprints leading inside.
One sentence horror story: I woke up in the middle of the night, and there was a figure at the foot of my bed. When I turned on the light, it was still there. It was my own reflection, but I was still in bed.
One story could be: 'I heard a knock on the door at midnight. When I opened it, no one was there, but I felt a cold hand on my shoulder.'
A third story could be 'I walked into the abandoned house. The moment I stepped in, the door slammed shut and the walls began to ooze blood.' The idea of being trapped in a place where something so grotesque as walls oozing blood occurs is terrifying. It plays on the fear of being in an unknown and dangerous situation, which is a common theme in horror.
The old doll in the attic blinked. Now it sits on my bed.
